When tapes are played to students (either in groups or individually) the students should be told to make notes of any word or phrase they do not understand so that they can refer to the Scientology dictionary, a general dictionary, or their technical materials for explanation.

The Supervisor should give a brief explanation if the word or phrase is at a higher level of training than the student is learning or refer student to the detailed definition to be found in publications if it is at the same or lower level.
